Douluo Continent: The Book of Witness and Peerless Tang Sect

Chapter 123 Solving the lighting problem, avoiding away games.

The paper in his hand wasn't small, but it didn't list many names of the core magic arrays. Long You was an expert in soul tools, and he easily deduced Lin Zhengze and He Caitou's city defense strategy from the types of these core magic arrays.

All of them are high-speed attack soul tools, not to mention heavy machine gun-type soul tools. Even the soul cannons that He Cai Tou and Cai Tou are preparing to build are combined rapid-fire cannons.

Whether the ammunition explodes or not is not important, but the number of attacks must be enough to cause an explosion. As long as the sandworms' attacks can be blocked at the city walls by a dense barrage, casualties will be minimized.

As for how to solve the problem of lethality, that is, how to solve the problem of high-speed soul-guided ammunition prioritizing penetration over lethality (heavy machine guns have large apertures and can shatter hard objects, but they are not particularly effective against soft-bodied animals, especially those that can survive being split in two). You could set it on fire!

Long You saw a lot of throwing devices on the list. Earlier, outside the blacksmith's shop, he also saw Xu Sanshi, who had been sent out to run errands, carrying a lot of materials that looked like they were for making incendiary bombs.

Therefore, Long You could now guess that He Caitou and Lin Zhengze were planning to use high-speed soul tools to intercept and divide the sandworm swarm, and then use flames to inflict damage. Whether it was throwing Molotov cocktails or directly spraying flames, the goal was to trap the sandworm swarm in flames.

"Senior Brother! Do you guys have any experience in making large-scale defensive shield-type soul tools?"

After looking at the list twice, Long You couldn't find the soul tool he was looking for, so he immediately shouted at He Caitou inside to ask.

"Yes, Senior Brother Lin and I are currently making them. We don't have time to make the high-level city shields that can protect the entire city wall with a single shield. We are making a linked city shield instead."

Twenty level-three city shields would be enough for one city wall. Those sandworms aren't strong offensively; their main strength lies in their strong devouring and corrosive properties. City shields perfectly counter their attack methods.

After He Caitou finished answering, Lin Zhengze also spoke up:

“My dear junior brother Long! Time is tight and the task is heavy. The list I’m giving you is the work you must complete within two hours, otherwise our city defense will be much more difficult.”

"What the hell? So many! In two hours? Are you crazy?! How is that possible?"

Okay, let's get to the point. What about the lighting soul tool? I checked before, there are no lighting facilities on the city wall, so what will they use for light at night? Torches?

"I know what you're trying to say, but those sandworms are far more afraid of light than you can imagine. Once they find a bright spot after nightfall, they'll swarm in and won't give up until they get what they want."

Even if we create searchlight-like illumination devices, once placed on the city walls, they definitely won't last long. After all, none of us currently have the capability to stand within the insect swarm for an extended period to protect the light source.

"Searchlights? Why do we need to make searchlights? We should make those floating, high-altitude light sources that can illuminate the area around North Frost City as bright as daytime."

Don't let the sandworms find the light source, or rather, let them mistake the light source for the sun during the day. Even if the sandworms still want to attack the light source, let them. The light source is floating in the sky anyway, and the sandworms can't fly; it's a waste of their energy, relieving pressure on the city wall defenses.

"A floating light source? What's that? Can you make one?"

"No, our college used to rely entirely on streetlights for lighting."

"Yeah, at most it's just a high-powered searchlight, I've never seen a floating light source before."

"Alright, I got it, I'll do it. Put the things on this list aside for now, we have to get a stable and reliable light source, otherwise we'll be playing away from home."

"Senior Brother Beibei, don't just sit around doing nothing, go make some flares. If the sandworms really manage to bring down the light source floating in the sky, I need flares that can hold out for at least an hour."

"clear."

Everyone present knew how crucial light was in dealing with dark creatures. The reason they hadn't addressed it before was simply because they felt there was no way to preserve the light source. Now that they had a solution, naturally, creating the light source was their priority.

The mineral reserves in Beishuang City are indeed very abundant. Although not all kinds of rare metals are available, most of the soul tools envisioned by Long You and others can be produced so far.

My arms ached, my fingers were stiff, my eyes were sore, my forehead was sweating, and my stomach was growling. The sky outside grew darker, but the blacksmith's workshop remained bustling with activity.

The large stealth soul-guided reconnaissance drone had already been completed and was operational. As the last glimmer of light disappeared on the horizon, the night-vision camera carried by the large stealth soul-guided reconnaissance drone transmitted back the scene outside the city.

Countless worms covered in layers of yellow sand crawled out from underground, and almost instantly, North Frost City was surrounded by a sea of ​​insects.

The residents of Northfrost City stood on the city walls, their faces expressionless. They knew that reinforcements had arrived in Northfrost City today, but they also knew that the number of reinforcements was small, even negligible.

They saw new things appearing on the city walls, but the feeling of despair remained unchanged. These residents of Northfrost City did not believe they could survive this disaster; what drove them to stand on the city walls every night was merely the inertia of the past year or so.

Inside the blacksmith's shop, Long You and the others were still busy, but they all saw the scene on the city wall through the images transmitted back by the large stealth soul-guided unmanned reconnaissance aircraft.

"They were lifeless and demoralized; these people had completely lost hope of living."

Fortunately, those who have survived to this day are all martial artists; otherwise, we would not have enough soul power reserves to use these soul tools.

Xiao You, is your light source ready?

"Three, two, one..."

“pong——whoosh——”

As the countdown in Longyou ended, a not-so-loud explosion rang out, followed by the sound of something breaking through the air.

The sounds of explosions and air being torn apart were already familiar to everyone; they were the sounds of artillery shells being fired. However, in the heat of the moment, no one knew where the soul-guided cannon was firing from.

Fortunately, before everyone could get nervous, soft but bright enough light began to stream down from the sky. At that moment, Long You walked in through the blacksmith's shop, carrying something that resembled a perfectly vertical mortar barrel.

"Let's see how it goes. Time was too tight, so I didn't pursue a higher level of soul tool. Instead, I used a star chain design to connect the low-level lights together."

The sky outside should be filled with a blanket of white stars right now.
